Effect of Adox on cell cytotoxicity in C3H10T1/2 stem cells. Cells were treated with different concentrations of Adox for 24 and 72 hrs. Cells in control were cultured in OB medium treated with (DMSO) as a solvent control (the final concentration of DMSO was 0.2%). The other cells were cultured in OB medium containing different concentrations of Adox (10-100 μM). Cell cytotoxicity was determined by MTT assay and expressed as a percentage of viable cells in the total number of cells counted. Values are means ± SD (n = 3) for each treatment.
